Working on a “d” tune for my truck. There doesn’t seem to be the openness about these ecm’s as there were in the previous models for whatever reason so I’ve been trying to figure it all out solo.

Just wondering if anyone can help me out with what the misc speed limiters are activated by or if they are even used? B2012 to B2016.

Also does anyone know if EFI alone has all the tables to do this and really make it rip and run well like tunes sold by tony and kory or does it require Hex work? First time really looking at it today. A bit overwhelming at this point lol.

I get it that a lot of the work to crack it was put in by the guys that sell tuning but so was the earlier years and once the stock files got out guys were openly sharing and doing stuff. Maybe it’s too complicated now so folks aren’t doing much tuning themselves anymore.

Everything is in there to 100% kill any and all emissions. No hex work required to get this done.

Right on
Thanks

I guess I’ll find out if those speed limiters do anything or not when I run it. I think I have all the tables changed I need to for a “d” tune including all the fuel limiters that have anything at all in their name tag pertaining to the stuff I no longer need activated so fingers crossed.

Still trying to convince myself to jump off the no more warranty bridge though lol. Once I have a box of shiny piping sitting in my garage though it might be easier.

Not a ton of risk with messing with those speed limiters, its pretty harmless. What year? Some of those trucks have an extra switch that pertains to messages

The Still Master
There are approximately 20-35 vane tables missing in the editor depending on the OS, and full/complete control of the fuel system requires finding all the rest of the missing hard and soft limiters and the drivers side rail control valve is not mapped as well as a host of other missing tables.

For the average guy/shop doing simple tunes the mapping in the editor is fine, but anyone who wants to even try to run a bigger turbo and or a CP3 conversion, and get it to run optimally you will be lacking many, many tables.

There are also a ton of hidden treasures not mapped in the many different segments that are worth having.

Are you saying EFI Live is missing these but you and others have found them and adjust them accordingly with your own magic program?

pretty much. They have been mapped out from the hex files and then uploaded to EFI Live via a .cax file and then used to tune in EFI Live from there. there really are secret/missing tables for the LML and sadly i dont see EFI Live ever fully mapping it. it certainly would awesome to buy the .cax files but im betting cost wouldnt be cheap as its not easy to find and map, and once sold/emailed, they can be shared quickly.

I find it odd efilive wouldn’t put more effort into it. There’s a lot of LML trucks out there. The longest running model of all the years to date with only a slight ecm change halfway through. Kinda takes the diy tuner out of the picture. Especially when you look at all the tables available in the lly compared to the later years.

I understand it’s costly to map, but I don’t mind paying a little more for a license to be able to do everything myself instead of being painted into a corner just because I want to do a cp3 swap. It also takes what made tuning fun and widely shared in the diesel motor sports world out of the picture for future folk. Basically, forcing everyone back to canned tuning. FN LAME!!

When the LML came out, EFI Live was going full bore in Cummins stuff and threw the LML on the back burner. They also said the ECM couldnt be flashed without opening it up. well we all know that changed over time and they started looking into the LML again but still kept precedence on the cummins stuff. The time never got devoted to the LML to really map whats needed. Hell even the LMM/LBZ stuff is missing tables. They just put stuff in that they and other beta tuners feel is needed or for what time is allowed on their schedule. This is not a dig at them. there is a point where the cost doesnt match the revenue and im sure there was other reasoning. The LML has substantially more tables as Tony pointed out and when/if they get the L5P opened up, it will be even larger. There is alot of competition out there now and more people would rather pay someone to tune their rig than do it them selves so i can see it being hard for EFI Live to generate the revenue needed to come back and revisit these platforms to and put the time in.

but we still had to use an unlock tool for the cummins for 5 years until EFI live decided to look into it. They are getting lazy

I think they're happy enough with what they've provided

For those with the roadmaps,creating cax files isnt too bad.

The stuff in the public release does really well for most guys

It seems that way. I’ve never looked at an EZ Lynk ecu editor but if they start offering more tables (and maybe already do) they might be the way of the future as they advertise.

Yes but many guys doing mods are swapping to cp3 along with everything else they change and as previously pointed out efilive apparently doesn’t provide the tables required to do this so they are in a sense cutting their own throat in v2 sales in the future. And I don’t see the l5p being any different in this regard. It really pushes the ease of use for the owner to just go with ez Lynk.

And most aren’t nerd enough to start using hex and making cax files to make up for the efilive shortcomings. It really is a shame.

Yes I agree, most shops don't have the capability to do their own hex work or cax add-ins.



Ez isnt going to be the future for small shops because their software still favors guys who do hex.



Ez has pre-loaded maps and then the capability to add in their own bins.



Where ez shines is the ability to protect your files from the general public by keeping people's hands off of them as individual files. But ez also sucks because you're uploading files to the "cloud" and I'm sure theres someone who has eyes on those

Like I said I’ve never looked at ezlynk ecu editor and don’t really know if their base tables are there to do what efilive alone can’t.

But if it can’t be done with efilive and the small shops need to go to a hex guy anyways for previous reasons why not just use ez Lynk? They can do the logging remotely without having to wait for the customer to send a log. Many of them already do just sell tunes bought from these guys anyways.

End of the day, like I said, efilive may be screwing themselves out of the future diesel market. Which maybe they don’t care about anyways.

Very interesting stuff for a guy that doesn't know how to tune and only purchases them. I do know that I have has 3 different tuners do my LML and there was always trouble getting the tunes to run properly. The last tuner hit it perfectly with his first try. Thanks Blake, appreciate it. What I have found the hard way is the TCM tuning is very important. If not tuned by someone that knows what they are doing, your tranny will not last long. Mine was built to handle 1000 + HP, and now I find that it's hurting because of wrong tuning.

Thanks for the kind words Gary. There is a lot to the LML compared to what everyone is used too on the LB7-LMM but then again it’s not rocket science. I enjoy it a lot. It’s more of a challenge I love taking them on. Glad your happy and once your transmission is refreshed your going to love it. It’s a shame that happened to you. Your not the only victim and will not be the last.
